COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 561,661, dated June 9,1896.

Application filed March 19, 1896. Serial No. 583,880. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK GARRAUX, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of 5 Georgia,have invented certain new and usef ul Improvements in Cotton-Presses, ofwhich the following is a specification.

My invention relates to that class of hidingpresses in which the sidesor doors of the bal- IO ing-chamber are separable for the purpose ofopening the baling-chamber to apply the baleties and to remove the bale.

My invention particularly relates to the devices for locking andunlocking the doors, and my object is to more securely lock and morereadily unlock the securing devices.

In the accompanyin g drawings, Figure 1 shows a perspective view of somuch of a cotton-press as is necessary to illustrate my in- 20 vention.Fig. 2 shows a transverse section on the line 2 E'- of Fig. 1. Fig. 3 isa detail view, on an enlarged scale, showing part of the lockingmechanism. Fig. 4: is a similar view of another part of the lockingmechanism.

The sills A are secured to the top beams B and to the cross-beams C byupright rods or posts D. These posts are connected at their upper endsby bars (1. The cross beams 0 0 are tied together by rods 0, and thesills are connected by the bottom piece E of the press. Rods F connectthe posts D together on opposite sides of the press, and on these rodsis supported a cross-beam G. A cross-beam H at the top of the press issecured to the posts D beneath the beams B. This construction justdescribed is common and does not form part of my present invention.

The hopper I is open at top and bottom. Three of its sides arestationary, while its front side J is hinged or pivoted at-j. Thishinged side J may be opened and closed and locked in either its openedor closed position by means of a swinging frame K, of wellknownconstruction.

The baling-chamber L is open at top and communicates with the hopper I.The bot- The two sides 0 and P need not be hinged, but are separablefrom the front and back sides. They are preferably provided with battens0 at their upper and lower ends. The top battens are adapted to fitbehind brackets Q, secured to the cross beams R on the upper ends of thefront and back doors M and N. At their lower ends the sides 0 areadapted to fit behind crosspieces S, secured to the bottom piece E. Thefront door M is provided with brackets T, constructed as shownparticularly in Fig. 4. These brackets are secured to the top beam R atopposite ends, and are slotted at t for a purpose hereinafter to bedescribed. The beam R on the back door of the press is provided withbrackets U, adapted to receive hooks on the locking devices now to bedescribed.

On each side of the press, above the side doors and outside thehaling-chainbcr, there is a sliding bar V arranged to move back andforth in guidebrackets 1'. At one end of each bar is hinged a hook o,adapted to engage with a bracket U. At the opposite end of each bar V ishinged a link t adapted to extend into the slot t of the bracket T. Theouter end of each link is hinged in a casting to on the end of aswinging frame \V.

Fig. 1 shows the balin g-chamber closed and by full lines shows thelocking devices in position to securely hold the four doors of thebaling-chalnberclosed and adapted to receive the strain of the press.The dotted lines show how the securing devices are unlocked. It willbe'observed that when in their locked positions the hooks -v engage withthe brackets U and the links r extend through the slots 15 of thebrackets T, the castings wbearing against the front of the brackets T.The pivots of the frame TV are in line with the sliding bars V when thepress is locked, and pressure on the doors will not cause thedisengagement of the locking devices. \Vhen, however, the frame TV israised to the position shown by dotted lines, the links n will be liftedout of the slots 6. The front door M may then be removed and the bars Vwill slide backward, relieving the strain on the hooks U, which may thenbe readily disengaged, and afterward the side doors may be removed.

In reassembling the parts the back doorh is first placed in position andthen the end doors are set up. Lastly, the front door is put inposition, then the hooks o are made to engage with the brackets U, andthen the links r are engaged with the brackets T.

The frame XV may be held in an elevated position by a hooked rod X,which may be attached to the upper part of the press or to any otherconvenient object.

The precise manner of constructing the frame of the press or of mountingthe doors is not important, as my invention relates eX- clusively to thedevices for locking and unlocking the doors. It will be observed thatthe devices are self-locking-that is to say, when the frame Vis elevatedto the position shown in dotted lines the doors are unlocked, but whendepressed to the position shown in full lines all of the doors aresimultaneously locked by this one movement of the frame. Internalpressure does not tend to lift the frame N and thus unlock the doors,because the pressure is in line with the pivots of the frame and doesnot tend to swing this frame in either direction.

I claim as my invention 1. A baling-press provided with separable doorssecured by bars sliding in guides on the frame of the press and havingthe hinged locking devices at their opposite ends detachably connectedwith the doors, and a frame for securing and disengaging the locking devices, substantially as described.

2. A baling-press having separable doors and provided withlocking-brackets at their upper ends, in combination with the slidingbars, the hinged locking devices at opposite 4. The combination, in abaling-press, of u the separable doors, the bars sliding in guides atthe sides of the press outside of the balingchamber, hooks on the barsadapted to engage with brackets on the doors and a swinging framepivotally connected with the bars in line with their longitudinal axes,substantially as described.

5. The combination of the separable doors, the brackets on the backdoor, the slotted brackets on the front door, the bars sliding in guidessecured to the baling-press outside the baling-ehamber, hooks hinged tothe sliding bars and adapted to engage with the brackets on the backdoor, links pivotally connected with the sliding bars and engagin withbrackets on the front door, and a swinging frame connected with thepivoted links, substantially as described.

In testimony whereof I have hereunto subscribed my name.

FREDERICK GARRAUX.
